STRUCTURAL EVOLUTION OF THE CHEKA PLUTON (SOUTHERN URALS): PETROMAGNETIC STUDIES AND FRACTURE ANALYSIS

Геодинамика и тектонофизика
The Cheka pluton, located in the Magnitogorsk megazone of the Southern Urals and composed of the alkaline granitoids, is meridionally elongated (1–2)×6.5 km. The fracture and anisotropy of magnetic susceptibility analysis was made on the Cheka pluton for

Weathering Trends Unveil K-Metasomatism in Bundelkhand Granitoids: Resolving the Pink–Grey Granitoid Paradox

The petrogenetic puzzle of pink coloration of granitoid rocks is rooted on the debate between primary magmatic versus metasomatic origin of K-feldspar, which, in turn, has persisted due to difficulties in distinguishing these processes through conventional petrographic methods.
